Avient's New Edgetek™ Materials Optimize Weld Strength, Flame Retardance and Aesthetics for Laser Welded Applications

Avient can provide materials compatible with the LDS (Laser Direct Structuring) process to achieve design flexibility and increased speed to market for base station antennas.

A M E R I C A & A S I A • Eliminate voids in plastic that create quality issues • Reduce high scrap rates due to sink marks • Improve low strength-to-weight ratio due to voids • Reduce long cycle times • Run more fractional melt / low melt flow resins • Improved cell structure and physical properties • Removed sink marks to reduce scrap rates • Improved gas retention when used with N2 physical foam • Reduced short shots for lower scrap rates • Improved melt flow and created a more controllable foaming process • Provided greater ability to process low melt flow resins Excelite™ IM Chemical Foaming Additives KEY REQUIREMENTS* WHY AVIENT?

Processors using Excelite IM additives between 0.12% and 0.5% can achieve density reductions, smoother surface finishes and reduced sink marks while generating a tighter cell structure. Utilized for weight reduction, sink mark removal or dimensional stability. PP, PE, PS, PVC No Good Foam PP Better, larger cells with lower cell density in standard IM processes; suitable for cell nucleation in structural foam processing PP, PE, PS, PVC Yes Better FA-110 Best cell structure with higher cell density; provides better structural integrity and lower density in standard IM processes PP, PE, PS, PVC Yes Best KEY CHARACTERISTICS Excelite IM formulations provide injection molders with: • Material density and weight reduction • High concentration of active CFA • Improved distribution of CFA into polymer matrix • High cell density with tight cell structure • Control over consistency and accuracy • Reduced sink marks • Ability to improve flow of material • Cycle time reduction • Improved dimensional stability • Improved thermal insulation EXCELITE IM – PRODUCT FORMULATIONS www.avient.com Copyright © 2020, Avient Corporation.

The gas expansion pressure supports the foam core structure formation while reducing the appearance of sink marks, as it expands from within. Sink marks and warpage are caused by material shrinkage in thick or asymmetric areas during cooling. Sink-mark With chemical foaming, no sink-marks Core-Back Expansion molding allows greater density reductions than typical injection molding.
